Purchased new when my child entered elementary school, and used once a year for disaster drills. As described below, there is considerable wear and tear, but I hope this will be helpful for those who want to collect a set, or for those who want a spare for home use. Please consider this, understanding the following: There is a used feel, with what appears to be dirt on both the outside and inside. I have done home cleaning, but the dirt-like marks did not come off. The rubber parts are stretched and twisted. The name section has been blacked out with a marker, and a 100-yen shop name tag sticker has been applied. It will be packed compressed to a thickness of 3 cm.
